True colour sensors

May 2003 Sensors & Transducers Products & Solutions

Banner Engineering is now offering its new QC50 true colour sensor that reliably analyses and identifies user determined colours. Unlike standard sensing methods which only detect light to dark contrast, the advanced Banner QC50 emits a modulated white light which when reflected back from an object is electronically filtered to its red, green and blue components for accurate colour determination. A powerful microprocessor and refined sensing optics outperform its contemporaries.

The QC50 offers colour-only and colour-plus-intensity sensing modes. Colour-only mode is ideal for sorting applications where the colour differences are obvious such as red or black or green and colour-plus-intensity mode refines the sensor's capabilities to include greyscale. This mode is used for batch sorting when identifying a specific colour from within a family is required such as light blue, medium blue or dark blue. "With discrete outputs for accurate detection of three unique colours and a responsive intensity mode, the QC50 is an excellent sensing solution for error-proofing, product sorting and colour verification applications that would otherwise prove too challenging for a standard contrast detection sensor," said Joe Dolinsky, technical manager for Banner's photoelectric products. "Now industries such as packaging, automotive, pharmaceutical, cosmetics, printing, semiconductors and quality assurance have a cost-effective option to provide reliable colour discrimination."

Programming the QC50 is straightforward. With its three independent output channels, the QC50 can be set to reliably detect up to three different user-defined colours and with a 335 ms response speed, the QC50 is suitable for integration into a high-speed production process. Two pushbuttons are used to make manual adjustments of the colour channels, sensing mode and tolerance levels.

A compact and flexible sensor, the QC50 has a rugged ABS plastic housing rated IP67 and will operate in temperature range: -10 to +55°C. A swivel disconnect fitting adjusts to three positions, allowing for convenient mounting and connection in confined areas. The 10 to 30 V d.c. QC50 has a maximum output rating of 40 mA at 24 V d.c. Models are available with a choice of three NPN (current sinking) or three PNP (current sourcing) outputs. They tolerate vibration and mechanical shock and are also protected against false pulse on power-up, continuous overload, and transient overvoltages.
